The Arc de Triomphe is a neoclassical triumphal arch located at the western end of the Champs-Elysees at the center of the Place Charles de Gaulle in Paris, France. It was commissioned by Emperor Napoleon I in 1806 to commemorate his victory at the Battle of Austerlitz and the French fallen from the French Revolutionary Wars and Napoleonic Wars, and construction began on 15 August 1806. It took two years to lay out the foundations, but construction was halted after the Bourbon Restoration; construction resumed under King Louis Philippe I in 1833, and it was completed on 29 July 1836. On 15 December 1840, the repatriated body of Napoleon I passed under the arch on its way to Les Invalides, and Victor Hugo's body was also displayed under the arch during the night of 22 May 1885 before he was buried at the Pantheon. The arch went on to be the site of triumphal parades, including by the Imperial German Army in 1871 after the Franco-Prussian War, the French Army in 1919 after World War I, the German Wehrmacht in 1940 following the fall of France, and the French and Allies in 1945 following the liberation of Paris. On 11 November 1920, an unknown soldier was interred under the arch of the Arc de Triomphe to symbolize the unidentified dead of both world wars, and it was the site of the first eternal flame to burn since the Vestal Virgins' fire was extinguished in the 4th century AD. Since its foundation, it has since become one of the most famous monuments in Paris.
